Introducing: The Formex Reef 39.5mm Automatic COSC 300M Forged Carbon

I am a fan of Formex. I like that the brand attempts to create the best-built watch within its chosen price category. The designs aren’t for everyone, but the build quality is undoubtedly excellent.

On both counts, they left me impressed, particularly given their asking […] Visit Introducing: The Formex Reef 39.5mm Automatic COSC 300M Forged Carbon to read the full article.

Watches & Wonders: The Chopard L.U.C. 1860 Chronometer, Like the Original from Three Decades Past, May be Worth The Wait Worn & Wound
Chopard L.U.C 1860 Chronometer Like Apr 14, 2026

Watches & Wonders: The Chopard L.U.C. 1860 Chronometer, Like the Original from Three Decades Past, May be Worth The Wait

Louis-Ulysse Chopard founded his eponymous watch company in 1860, but it took over 100 years for the brand to truly come into its own. In 1996, and after three years of development, the company debuted its own in-house movement. The wait seemed to have been worth it. The L.U.C 96.01-L immediately drew acclaim for beautiful finishing, embracing the microrotor, and COSC certification. It, and the subsequent L.U.C. 1860 dress watch, marked a sea change from reliance on third parties to true independence, arriving at a resurgence in fine mechanical watchmaking. Thirty years later, the L.U.C. family has expanded into dozens of variants, complications, and movements. But at 2026’s Watches & Wonders, Chopard pays tribute to 30 years of in-house manufacturing with a continuation of that vaunted original. The L.U.C 1860 Chronometer uses the same dial and microrotor movement from 1996, albeit with their own upgrades and unique design tweaks.  The intricate white-gold dial features guilloché finishing in the center, emanating in scalloped waves from the Chopard logo and nameplate. The concentric circles are separated by thin bands of white gold, and delicate spear-shaped markers point inward, toward the dauphine hands. At 6 o’clock, the small-seconds dial echoes the twin-circle pattern of the overall dial, and Chopard specifically mentions the lack of a date window “to preserve purity.”  Where the first L.U.C. 1860 had a white dial with gold accents, this Chronometer wears...

Hands-On: TAG Heuer Monza Flyback Chronometer

LVMH Watch Week, the year’s first significant watch fair, just kicked off in Singapore. In some ways a warmup for Watches & Wonders in March – the biggest watch fair of the year – the LVMH Watch Week is where the watchmakers owned by the French group show off their wares. Amongst them is TAG Heuer, which has revived one of its less-known racing chronographs from the 1970s but in a thoroughly modern style. The Monza Flyback Chronometer is a flyback chronograph featuring an open-worked dial and a 42 mm carbon composite case. Initial thoughts Perhaps the most aggressively modern chronograph in TAG Heuer’s current line-up, the new Monza liberally reinterprets the 1970s original. While the vintage Monza is not famous as the Carrera or Monaco, it is interesting in several respects, including the fact that it was the first serially-produced Heuer to sport a black-coated case. The carbon case and open-worked, asymmetrical dial show another face of TAG Heuer, but one that still fits with its motorsports-chronograph heritage. Certainly a TAG Heuer that is different, the Monza has clearly been conceived to cater to contemporary tastes, which is a good thing given that TAG Heuer already has an ample offering of faithful vintage remakes. But the new Monza comes with a caveat, a steep price. Coming in at US$13,500, the Monza costs double the Autavia Flyback Chronograph that has the same movement but a no-frills steel case. Even considering the carbon composite case and fanc...

In-Depth: The Longines Observatory Chronometer Cal. 360

In the field of precision timekeeping, one inevitably encounters Longines with its multi-facetted and remarkably rich history. The unwavering persistence of the firm’s celebrated régleurs and its long lineage of in-house chronometer calibres fostered Longines’ reputation for excellence in precision timekeeping, far beyond the borders of Switzerland. The Saint Imier-based manufacturer ventured into precision chronometry as early as 1888, amidst the dawn of observatory chronometer competitions in Switzerland, when its cal. 21.59/60-based chronometer obtained an observatory-issued Bulletin de Marche, or rate certificate. And after almost a century of steadfast participation in prestigious chronometry trials, the last Longines timepiece subject to observatory-governed testing, a cal. 262 based chronograph (movement no. 14’701’394), received its certificate in 1972. The Neuchâtel observatory announced its first chronometer contest on December 5, 1865. Eight decades later this Longines advertisement portrayed the observatory chronometer contests as an uphill battle, referencing the record of N=5.00 obtained by the wristwatch-sized cal. 15.68Z in 1945 at Neuchâtel. Towards the end of the 1950s, a pure-bred competition calibre named the cal. 360 became Longines’ final masterpiece in the hard-fought race for glory in precision. A proven workhorse that won countless prizes and accolades at both the Neuchâtel and Geneva observatory competitions, the cal. 360 was a pu...

Up Close: Glashütte Original Senator Chronometer Tourbillon

One of the more interesting complicated watches launched in 2019 was a surprising one, the Glashütte Original Senator Chronometer Tourbillon. While “Chronometer Tourbillon” might seem to be a pair of impressive words meaninglessly strung together as is often done for high-end watches, the Chronometer Tourbillon actually takes them seriously. Though the new watch doesn’t look particularly interesting – the design is handsome but conventional – it combines a particularly logical set of complications that were conceived for exact setting of the time, namely a hacking tourbillon with zero-reset carriage (and not just the seconds hand), and a minute hand that is set in discrete, one-minute steps. In fact, the Chronometer Tourbillon derived from the already sensible, but less fancy, Senator Chronometer that has many of the same time-setting functions. Though the Chronometer Tourbillon is an expensive watch by the standards of Glashütte Original, it is eminently sensible and smart from a technical perspective. And to prove that chronometric competence, Glashütte Original also tests the Chronometer Tourbillon to the German chronometer standard, DIN 8319, laid out by the country’s all-encompassing federal standards body. Testing takes place at the Sternwarte Glashütte, the town’s astronomical observatory, which was given a new lease of life by German watch retailer Wempe, which also has its own line of chronometer wristwatches. The process, however, is conduc...
